15 # These directives are mandatory. The machine directive specifies the
16 # platform and the machine_arch directive specifies the cpu architecture.
23 # This is the ``identification'' of the kernel. Usually this should
24 # be the same as the name of your kernel.
29 # The `maxusers' parameter controls the static sizing of a number of
30 # internal system tables by a formula defined in subr_param.c. Setting
31 # maxusers to 0 will cause the system to auto-size based on physical
37 # The `makeoptions' parameter allows variables to be passed to the
38 # generated Makefile in the build area.
40 # CONF_CFLAGS gives some extra compiler flags that are added to ${CFLAGS}
41 # after most other flags. Here we use it to inhibit use of non-optimal
42 # gcc builtin functions (e.g., memcmp).
44 # DEBUG happens to be magic.
45 # The following is equivalent to 'config -g KERNELNAME' and creates
46 # 'kernel.debug' compiled with -g debugging as well as a normal
47 # 'kernel'. Use 'make install.debug' to install the debug kernel
48 # but that isn't normally necessary as the debug symbols are not loaded
49 # by the kernel and are not useful there anyway.

595 # SCSI DEVICE CONFIGURATION
597 # The SCSI subsystem consists of the `base' SCSI code, a number of
598 # high-level SCSI device `type' drivers, and the low-level host-adapter
599 # device drivers. The host adapters are listed in the ISA and PCI
600 # device configuration sections below.
602 # Beginning with FreeBSD 2.0.5 you can wire down your SCSI devices so
603 # that a given bus, target, and LUN always come on line as the same
604 # device unit. In earlier versions the unit numbers were assigned
605 # in the order that the devices were probed on the SCSI bus. This
606 # means that if you removed a disk drive, you may have had to rewrite
607 # your /etc/fstab file, and also that you had to be careful when adding
608 # a new disk as it may have been probed earlier and moved your device
609 # configuration around.
611 # This old behavior is maintained as the default behavior. The unit
612 # assignment begins with the first non-wired down unit for a device
613 # type. For example, if you wire a disk as "da3" then the first
614 # non-wired disk will be assigned da4.
616 # The syntax for wiring down devices is:
618 # device scbus0 at ahc0 # Single bus device
619 # device scbus1 at ahc1 bus 0 # Single bus device
620 # device scbus3 at ahc2 bus 0 # Twin bus device
621 # device scbus2 at ahc2 bus 1 # Twin bus device
622 # device da0 at scbus0 target 0 unit 0
623 # device da1 at scbus3 target 1
624 # device da2 at scbus2 target 3
625 # device sa1 at scbus1 target 6
628 # "units" (SCSI logical unit number) that are not specified are
629 # treated as if specified as LUN 0.
631 # All SCSI devices allocate as many units as are required.
